With your OHP, Kels, do you have access to a lighter barbell or do you have to go straight to the 20kg? This irritates the heck out of me, at the gym, because there's no light warm-up option available in barbell form.

There are lighter barbells as well. I was already pretty warm from the benching so I didn't worry about using them. That would be very irritating though! Does that mean it's the same for bench accessory work, like skull crushers?
